What to check before viewing
The model's most common MOT issues, turned into things you can ask about or look for.
Brake discs
High priorityAsk for the date and mileage of the last disc replacement; visually check for a deep wear lip and rust pitting on each disc.
Suspension bushes and joints
Worth checkingListen for knocks over speed bumps and ask about recent control-arm or anti-roll-bar work.
Leaks
Worth checkingInspect the leaks carefully and ask the seller for repair history.
Tyres
Worth checkingCheck tread depth across the full width on all four; uneven wear suggests alignment or suspension issues.
Suspension springs
Worth checkingCheck ride height is even side-to-side and look for cracked or rusted coils.
Vehicle-specific check
Worth checkingCheck the car’s number plate on MOT Wise to see its own MOT history and any recalls for its build years.
